" Host-guest chemistry is an important vehicle for characterizing the factors involved as molecules react. Two recently published Nobel lectures presents fascinating overview that takes the reader from Pedersen’s original discovery of macrocyclic ethers through the preorganization and structural recognition in Cram’s early studies to more recent uses of hosts as enzyme mimics and synthetic molecular vessels.

" Acid rain, tropospheric ozone depletion, and forest damage represent significant environmental problems. A recent article summarizes elementary chemical processes involved in the generation of oxidants under wet and dry conditions; it also provides a summary of mathematical modelling...
